Subject: ALSA: hda - Add missing terminating entry to SND_HDA_PIN_QUIRK macro
From: David Henningsson <david.hennings...@canonical.com>
commit fb54a645b2739fb196446ffbbbe3f3589d117b55 upstream.
Without this terminating entry, the pin matching would continue
across random memory until a zero or a non-matching entry was found.
The result being that in some cases, the pin quirk would not be
applied correctly.
